Bug check description: This indicates that a kernel-mode program generated an exception which the error handler did not catch. This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: nv4_disp.dll (NVIDIA Compatible Windows 2000 Display driver, Version 280.26 , NVIDIA Corporation).
